Abstract

The present invention relates to a process for production of unsaturated ω-3-fatty acids and to a process for production of triglycerides with an elevated content of unsaturated fatty acids, especially of ω-3-fatty acids having more than three double bonds. The invention relates to the production of a transgenic organism, preferably of a transgenic plant or of a transgenic microorganism, with an elevated content of unsaturated ω-3-fatty acids, oils or lipids having ω-3-double bonds as the result of the expression of an ω-3-desaturase from fungi of the family Pythiaceae such as the genus Phytophtora, for example of the genus and species Phytophtora infestans.
